Major seventh chord construction

Construction of the major seventh chord.

A major seventh chord is constructed by adding a major third on top of the perfect fifth of the major triad.

The new interval – perfect fifth (5) + major third (3) – is equal to the interval major seventh (7).

A minor seventh chord is built of a major third + a minor third + a major third.

Another way to end up with a major 7th chord is by picking every other note in the major scale.

  • Major scale intervals: 1, 2, 3, 4, 5, 6, 7.
  • Major 7th intervals: 1, 3, 5, 7.
F -> Fmaj7
Add the major seventh interval (7) to the F major triad and F becomes Fmaj7.
